Evaluating Forgetting Curves
A new method is described for determining the effect of original learning (or any other variable) on forgetting. The major question is, How much forgetting time is required for memory performance to fall from any given level to some lower level? If this time is the same for different degrees of original learning, then forgetting is not affected by degree of original learning. If this time is gr...
متن کاملQuantitatively Evaluating Formula-Variable Relevance by Forgetting
Forgetting is a feasible tool for weakening knowledge bases by focusing on the most important issues, and ignoring irrelevant, outdated, or even inconsistent information, in order to improve the efficiency of inference, as well as resolve conflicts in the knowledge base. Also, forgetting has connections with relevance between a variable and a formula. However, in the existing literature, the de...
متن کاملGenuine power curves in forgetting: a quantitative analysis of individual subject forgetting functions.
Wixted and Ebbesen (1991) showed that forgetting functions produced by a variety of procedures are often well described by the power function, at-b, where a and b are free parameters. However, all of their analyses were based on data arithmetically averaged over subjects. R. B. Anderson and Tweney (1997) argue that the power law of forgetting may be an artifact of arithmetically averaging indiv...
متن کاملForgetting Curves Emerge from Dynamics of Integrated Memory
We present a Dynamical Integrated Memory Hypothesis (DIMH) and illustrate its use by arguing that forgetting curves are emergent properties of dynamical memory that includes decay and influences of complex context on memory traces. Because forgetting curves are emergent, it is not likely that a single simple function will be able to model them. Forgetting at different time scales is similar bec...
متن کاملEvaluating Intelligent Tutoring Systems with Learning Curves
The evaluation of Intelligent Tutoring Systems, like any adaptive system, can have its difficulties. In this paper we discuss the evaluation of an extension to an existing system that uses Constraint-Based Modelling (CBM). CBM is a student modelling technique that is rapidly maturing, and is suited to complex, open-ended domains. A problem with complex domain models is their large size, necessi...
